You didn't expect to be thinking of your husband, while pinned beneath another man.

What was meant to be a simple capture mission for a wayward Curse user, had instead exposed a stunning weak point in your skills.

You'd expected Cursed techniques, not a fist-fight. This showed, when you'd been put in a chokehold, thrown to the ground, and felt the blind panic of the Curse user climbing on top of you, reaching down with a dirty little smirk, to put his hands around your neck. Images of Kento; smiling, his arms around your waist, reading in the sun-dappled grass, always victorious in hand to hand combat, flooded your mind, suddenly blinded by memory--

Thank goodness for the boy.

"O-oh shit-- Mrs.Nanamin--!"

You had barely a moment to register the nickname, before your deadly boy of peaches and punches dragged the Curse user off you. On your back, panting up at the ceiling, you listened to the coordinated thumps and grunts from the next room, as Yuuji beat the Curse user like a sack of flour.

Silence. Footsteps. Peach fuzz, leaning round the corner.

"...Mrs.Nanamin?"

"That's Mrs.Nanamin-sensei to you, kiddo."

Yuuji grinned, reaching down, and you let him pull you up. Your cheeks were flushed, angry with mortification, prickling beneath the crippling weight of being so weak. Yuuji looked awkward, rubbing the back of his head. You huffed to the next room, trying to drag the unconscious Curse user like a bag of potatoes.

You huffed again, angrier this time as you shouted to nobody in particular, the stress of memory coming out sideways.

"God, why am I so FUCKING USELESS--"

After the latest batch of negative pregnancy tests, your morale was low.

"Six months, Kento!" You cried, each month longer than the last as you flurried round the kitchen with tears in your eyes. Kento stood in silence, holding court for your rage and bitter tears, his arms folded across his chest.

You slammed the bin too sharply, swung cupboards open with a crack, flicked the kettle on like it was personal. Kento waited for your disappointment to abate, before he spoke, low and slow.

"...it's normal, my love. I know you're disappointed. But we'll get there. Six months isn't that long. Sometimes...these things just take time." You bristled, turning on him, your lip crumpling up.

"Are you not disappointed?" Kento looked at you over glasses that weren't there, reading, unfighting in a way that left you exposed. He walked to you, his words blanketing.

"Not with you. I haven't lost anything. I just have a little longer to look forwards to something new." Kento's arms slipped round your waist, a nuzzle against your ear, taking your vulnerability and cradling it in his palms. "Is that so bad?"

You deflated, the fight loved out of you. You looked at the pregnancy test on the counter, and its stark single pink line. You whispered, in part to Kento, and in part to yourself as he lifted you onto the counter, settling between your legs like it was home.

"...no. I suppose it's not so bad."

When Nanami Kento had offered to teach hand-to-hand combat at Jujutsu High, they'd leapt at the chance. Principal Yaga bore down over Kento while Kento looked round in alarm, willingly signing the contract he had asked to sign.

These simulated fights, so much safer than the real fights, kept Kento closer to you in a way you needed, viscerally. He'd miraculously walked out of Shibuya with nothing more than cuts and bruises, but it did little to ease your terror of having almost lost him.

You searched the school, following the blue-fire feel of him in the air; you followed the trail, as if grasped by a yellow spotted tie, silkwrapped around the palm of your hand, pulling you to him. You found him, panting with sweatsheen arms, beginning to tidy equipment in the empty gymnasium.

Kento looked up as you approached; in a white vest, and grey joggers, barefoot, his hands were wrapped with white tape, dusty with chalk. With his sweatslick honey hair swept back, his crooked smile rerouted a droplet of sweat on the way down his jaw.

"Lover." Kento greeted, low and husky, his voice scratchy from the heat of simulated battle. You leaned against a stack of gym mats, smiling, in your own gymwear.

"Been beating up children again? Who was it this time?" Kento chuckled, gravelly, lifting a medicine ball to the side with shocking ease. Your eyes traced his bare arms, and the undulating shift of corded muscles there, thick and powerful.

"Fushiguro. He asked for it." You laughed, as Kento dusted his hands together, chalkdust puffing into the air. Kento smiled again, still crooked, huffing a laugh. "No, he really did."

"I should think he regrets that."

"He's learned some important lessons."

"Like, the way to Shoko's office?"

"Yes. Amongst others, I hope."

Silence sat between you both, as Kento leaned back against the gym mats beside you. He held court again, this time for your unasked questions.

"...Kento. I...need some help. I'm, uh...lacking."

He was silent, still. You looked sideways, to find his eyes roaming the length of your body, caressing. Kento still thrummed with the testosterone and adrenaline of the fight; you could taste it, rendered primal by nature.

"...are you? I wouldn't agree." He hummed, keen eyes now zeroing in on his favourite parts of you, undressing you. You tried not to shudder at the unexpected heat pooling between your legs. When you spoke again, your tongue felt thick, rendered stupid by Kento's biological warfare.

"I'm...dreadful at fighting. Hand-to-hand combat. I'm too reliant on my Cursed technique." The respect with which Kento listened did nothing to mask the disrespect in his eyes. His grey joggers left nothing to the imagination.

"And...you want to learn, I assume." God, that voice, so much rustier than usual, sent daggers straight through your--

"Yeah. Yep. Yes. You assume right. I need...need you, uh...to teach me." You chirped, shaking off that second heartbeat, turning to face him.

You continued turning, magnetised as Kento held your gaze. He walked backwards onto the gym-mats, still marked by chalk-dust art of the animated human form. You swallowed, and Kento's eyes swam with something altogether more dangerous than desire alone. He widened his stance, his hands raised in preparation.

"Well...why don't you show me what you've got so far? As a baseline." You blushed, suddenly awkward in your body as you walked over to the mat, facing him. Kento had schooled his facial expression to his usual flat impassive gaze, but noticeably more shark-like.

"Like...just...come at you?"

"Mhm. Hit me."

You raised your hands, awkwardly balling them into fists, taking a step closer. You flushed at the microflexes of preparation that rippled over Kento's body, suddenly burning alive as you cocked your arm back, and--

"Thumbs out."

"Uh...sorry?"

Kento looked over absent glasses again. "Thumbs out. If you hit someone with your fists in your grip, you'll break your thumbs."

"Ah...right, okay." Being taught by Kento made you run hot, strangely submissive in the assumed teacher-student role. The heat only worsened with the way he was looking at you, fuck, I'd be done for if he really were my teacher--

You jabbed, darting forwards, a fist straight towards Kento's face. In a split second, he dipped sideways, stepping into a grab, and looped your arm behind you as you gasped, his other arm in an arresting grip around your neck, his body flush to yours from behind. You felt his breath, hot against your neck, and you shivered from hairline to toes.

"Plan your second move." Kento murmured, his lips against your ear, grazing you...tasting you. "You left yourself...wide open."

"Wide...wide open." You gasped, your vision swimming with the power of Kento's forceful restraint, biology overtaking sense and feminism as your clit throbbed. "O-okay."

Kento hummed against your ear, releasing you with what you felt was the briefest reluctance. He barked at you, his face sterner now-- "Again." --his eyes burning into you as you prepared yourself.

You punched again, this time towards his belly with a low-blow. Kento grunted, and you squeaked as he took the hit without flinching, your hand hitting concrete surely that is a brick fucking wall not a man at all shit--

You felt your legs swept from under you, and landed flat on your back with a bam, crying out and wincing, before opening your eyes. Kento prowled around above you, panting with something other than exertion.

In truth, if you hadn't shown up, he'd have been fucking his fist in the showers. While fighting in itself did not thrill Kento, the resulting burst of testosterone in the adrenaline comedown left his cock rigid and pulsing in a way that pissed him off.

He had not been able to shower; had not been able to lean on his forearm, cursing under the hot water as he furiously stroked himself in his hand, and imagined it was your cunt instead, still yet to quicken his seed within your belly, leaving him feeling somewhat lacking in a way he would never let you know but god he wanted you round and full and blooming so he could fill you again and prove you were his and--

"You can do better than that." Kento growled, something twitching in his jaw. Your chest heaved, looking up at him with glistening doe-eyes that went straight to his cock. He turned as he paced, swallowing hard, running a hand through his hair. "Get up. Lie there on your back, and someone will pin you down."

You stood on shaking legs, wondering how Kento seemed somehow bigger than usual. He stood opposite you again, electrified and taut. The same current passed through you again, and again, and again. You wondered vaguely, how to verbalise how you really wanted him to fight you and to make sure you didn't win so he could take his spoils from your body just as he pleased with you pinned and wet beneath him--

You swung your leg, turning sideways as you kicked...straight into his awaiting grasp. Kento grunted, your ankle under his arm, and drew you in, reeling you in by your leg as you hopped, crying out.

He couldn't disguise the wolfish smirk on his face by this point, and you yelled, laughing, until he reached your thigh, dropping you to the floor and pressing himself between your legs with a satisfied grunt.

"Left yourself open aga--oof--" You took Kento by surprise, rolling him over with your hips, straddling him on the floor. Kento coughed, the briefest how dare you on his lips as he pinched your inner thighs until you gasped, flipping himself on top again.

"--c'mere-- stop squirming-- shit, when I get you--"

"--come on Mr.Nanami, thought you-- fuck-- thought you were-- meant to be good at this--"

Any serious attempt at an education had turned into playful grappling, all hushed giggles and gasps, and Kento's heavy breaths against your skin as he tried to pin you down, too squirmy for him, every inch of you brushing against his rigid cock in a way that drove him mad, growing brittle, more dominant by the second.

Kento groaned against your neck, panting, bear-hugging you.

"--got...haaah...got you-- now-- fuck, stop fighting me--"

You tumbled around each other, your hits growing more powerful as his hands shook with restraint. You tried to crawl away as he dragged you back by your ankles with a growl, pressing into you from behind, and you bucked, throwing him off. Kento cursed, spitting feathers as you kicked out madly, grasping your ankles and pulling them apart so he could pin you down with his hips.

You flipped yourself over with a squeak, trying to claw yourself away, and Kento took his opportunity. He crushed you to the floor from behind, caging you, one thick arm looped around your neck as his whole body heaved with effort.

You stilled, just a little mouse in his jaws, as you felt the twitching heavy length of him rutting lazily into your arse. You felt the blood drain from your head, all the way down to your pussy, leaving you plush and throbbing and ready. You clawed at his forearm, half-hearted, hearing him rumble against your neck.

"--got you...I've got you...fuck..."

"K-Kento...please-- please--"

You squeaked to feel Kento's sharp canines sink into the back of your neck, your squirming only drawing out his groan into something needy and desperate. You felt his other hand trail downwards, cupping the whole length of your pussy from behind, trying to feel the shape of you through your thin gym clothes. You shivered, gulping against his arm.

"Please what?" Kento groaned, his hand reluctantly leaving your pussy to start to inch your gym leggings down, pawing and kneading at the plush of your hips on the way. You shivered, submitting with a bite of the lip, choking out around his arm.

"Please...fill me up...Kento."

Kento groaned, low and long. You felt him nuzzle against the shell of your ear, dexterous hands now yanking your gym leggings down, flinging them aside with conviction.

"Again. Say it again."

"P-please fuck a baby into me, Kento--"

Kento clapped a hand over your mouth, cursing as your hot little breaths leaked out through his fingers.

"You...you only think you know how much time I spend obsessing over it." Kento whispered, husky with desperation. You shivered to feel thick, calloused fingertips begin to tease between your folds, pinching and rolling the flesh around your clit until you whimpered under his hand. "Every day, getting up for work, when all I want is your hips lifted on pillows, so I can fuck myself empty into you again and again."

You felt Kento's fingers increase in pace, rolling, massaging rolling your pert little nub between his fingers, pleasuring you completely, until the itch of bliss started to creep through your hips and belly.

"F-fuck, Kento...please just...just..." You squirmed, wanting to be stretched, and worn by him, placing your pleasure behind duty. Kento bit deeper into the back of your neck, pinning you harder in chastisement.

"Just...just...what? Just fuck you?" Kento laughed, a dry little scoff behind your ear. He pressed a lingering kiss to your temple, his fingers working with expert knowledge of your twitches and jerks, guiding you by the hand towards your orgasm. "No...we won't be like that. We won't...put aside enjoyment just for the sake of a positive test. No...you'll cum when I say you'll cum."

You mewled, feeling his hand clap over your mouth again to muffle it, shushing you gently, a cautious eye glancing towards the door through his shuddering breaths. Kento's grey joggers did little to disguise the heavy weight of his cock, swollen and needy, with beads of pre-cum gradually darkening the fabric around the tip.

"Be as loud as you like at home...but here? You already interrupted me coming in my hand in the shower--" Kento continued through your squeak of alarm, "--but I won't be interrupted again. Need-- need to cum inside you. Sorry...shit, feel so wet-- good girl--"

Your vision went hazy, your breaths fracturing. Your clamping thighs and arching did little to slow the pace of Kento's fingers, dragging you over the edge like you were on rails. Feeling him pinch and roll your wet fleshy clit, your pussy clenched around nothing as you came with a whimper and a cry, trying desperately to buck anything inside you.

Before you'd even finished your peak, you heard Kento cursing and growling, removing and then replacing his hand for just long enough to press his weeping tip to your entrance, and rub you through the rest of your pleasure.

You squealed aloud beneath the insistent pressure of Kento's hand, as his cock fucked in ragged thrusts through slick cheeks and puffy folds, before burying to the hilt with desperate urgency. Being filled partway through your peak, to the soundtrack of Kento's growling curses, turned your ecstasy lightheaded, your ears ringing as you felt him fuck against your soft spot, barely pulling out.

"...mmmfff...K'n...oooo..."

"Sorry." He gasped, not sorry at all as lights fizzed in his eyes. "Missed that. Bit busy...fuck--so tight--make you tighter--"

Kento kicked the ankles of your outstretched legs to cross, and groaned, deep and guttural, to feel you squeeze his cock even tighter. He bit into your shoulder, crushing you harder against the gym mat with his brisk, deep thrusts.

Kento didn't let you come down, his fingers continuing to rub from side to side over your clit, swiping over the sensitive nub and the deeper wings beside it with such speed, the pleasure burned as one, consuming you in holy fire. You clasped at the hand and arm over your mouth, twitching and convulsing with such savage pleasure, that Kento rendered you base, animalistic.

"--g-good girl...good girl-- shit, pussy sucks harder than y-your mouth...take it. Sh...shit-- take it--"

Your husband had been replaced, spitting dirty talk like venom, his handsome face twisted into something monstrous, needier than you'd ever seen him. Kento slammed into you as though he were a man who needed to prove something to himself-- to you.

You couldn't work out where one orgasm ended and another began, but Kento could. As you moaned behind his hand, your throat sore with whimpers, Kento gasped, shuddering as his thrusts lost coordination, yanked against the hook behind his navel.

"--that'sit...unngghhhhn f-fuck...I'm...I'm..."

Kento rumbled into broken groans, complete and fracturing above you, feeling his orgasm roll through him in thick, sticky waves. He only hoped, vaguely, that it was deep enough, or good enough, or simply enough, his lips pressed in reverence to your sweaty temple as he filled you in moaning pulses.

You panted together through your comedown, Kento's hold on you unchanging, but somehow transforming into an embrace over an arrest. You stroked his forearm, and jolted to feel his fingertips probing around your entrance, fingering the cuff of your flesh around the base of his cock, still buried inside you.

"--au-augh K-Kento...what--"

"Shhh...don't move."

As you stilled, trying to slow your heaving breaths, you heard Kento shudder and groan as his softening cock slipped out of you. His fingers waited at your entrance...waiting for something--

As soon as the thick ooze of his cum reached his fingertips, Kento caught it, fucking it back inside you as you squealed, mewling and clenching, hypersensitive. Kento hyperfocused on the squelch of your cunt like a man possessed, pressing his seed deeper and deeper.

"...just...allow me to..." He breathed heavily against your neck, pinning you down harder as you bucked and squirmed, "...make sure...that my cum is in exactly the right place--"

You stilled with a guttural groan when Kento's fingertips curled forwards, finding the dimpled opening of your cervix and urging his release towards it. Kento laughed, delirious, breathless in your ear.

"...shit...heaven's gate, hmm? Let's feel her suck it all up..." Kento snaked his other hand beneath you, releasing your mouth to primal gasps, and he had the audacity to tut at you when you whined, as he began working on your clit again, treading softly, gently. His first hand still plugged inside you, his wedding ring slippery with your cream, he began to rub your clit to orgasm again, eager to feel you clench and gulp his seed deeper.

"...got to--got to get tougher with this...shit-- can't stand...seeing you upset, I...get this in your belly if--if it's the last thing I do...you can take it, can't you? Mmm...proud of you-- good girl--"

You could do little but dig crescents into the gym mat with your fingertips, prone as Kento worked you with methodical madness, with both of his hands. Effortlessly, he pushed you past juddering hyperstimulation towards another orgasm, ruinous in its scope, making your belly ache with syrupy-sweet contractions.

Kento marvelled, his jaw going slack and eyes fluttering closed as he felt the twitches of your cervix against his fingertips, and the way your pussy sucked his seed upwards, his fingers ensuring it had nowhere else to go. He let you whimper and convulse this way, shuddering to think of his cum painting your womb.

"--give you a baby-- give you what you want...I...no more disappointment, I swear, I-- fuck, you goddess, I-- love you so much, lover, good girl..."

You flopped, dopey on the comedown, shivering as Kento reluctantly slid his fingers out of you, satisfied to see no more of his cum seeping out. He kissed you, overcome with longing, and peppering it over your eyes, your cheeks, your lips.

"I adore you." Kento intoned, and you believed every ounce of the weight of his love. You swallowed thickly, turning yourself to cup his cheek, faux-stern as his eyes glimmered down at you.

"You...were supposed to be...teaching me how to fight." Kento hummed, chuckling, enjoying the way your jaw dropped as he licked his fingers clean.

"Yes, well...another time, perhaps. For now...I'm sure the showers are free, Mrs.Nanami."
